Figure 13 is a plan showing a V'modiiicait forms a barrier 'extended across the high- M tion, parts being broken away; way G. A link 32 1s pivoted to the lower end of the rod 29 and to the crank 25 of the shaft 23. A strong compression spring 33 is disposed in the cylinder 26. The lower end of the spring 33 engages the cylinder 26, and the upper end of the compression spring engages the head 30 of the rod 29.

Figure shows that oppositely-disposed depending spring latches 34 are secured at their upper ends to the cylinder 26. On the lower ends of the latches 34, there are proj ec` tions 35. The projections 35 extend through holes 36 in the cylinder 26 into the path of the head 30 of the rod 29. A cross piece 37 is secured to the cylinder 26. The pulleys 3S are journaled on the cross piece 37. The branches 39 of a crotch line 40 are connected to the lower ends of the spring latches 34. The branches 39 are rove over the pulleys 3S. The crotch line 40 is connected (Figure 6) to a crank 41 (Figure 7) on a shaft 42 mounted to rock on the tie 4. On the inner end of the shaft 42 there is a crank 43. The crank 43 is engaged with a depending hanger 44 (Figures 2 and 8) on an upwardly-iiexed wheelaetuated resilient member 45 extended lengthwise ofthe rail 1, iu close relation with the rail l. The wheel-actuated member 45 is connected at 46 by a pin-and-slot mechanism, or in any other suitable way, with the ties 3, so that the member 45 can spring up and down.

If a train is going in the direction of the arrow A. in Figure 1, the wheels of the train will run over the ramp 7 and depress it, rotation being imparted to the corresponding shaft by way of the crank 14` the crank 16 operating the rod 17, and rotation being imparted to the shaft 23 by way of the rack 18 and the pinion 22. When the shaft 23 is rotated as aforesaid. it assumes the position of Figure 6, the crank swinging down, and the link 32 pulling the rod 29 and the head 30 down, this operation perlnitting the gate 47 to close across the highway 6.

Then the head is pulled down into the position of Figures 6 and 10, it causes the spring latches 34 to carry the projections 35 inwardly on top of the head 30. The gate, thus, remains closed until the train runs on the wheel-actuated member' 45 and shoves it down. Then rotation is imparted to the shaft 42 of the crank 43 and the crank 44 of Figure 5, and the arm 41 on the shaft 42 pulls on the crotch line 40, the branches 39 of the crotch line running over the pulleys 38 (Figure 10) of the cross piece 37, and pulling the projections of the latches 34 out from above the head 30 of the rod 29. The spring 33 now reacts on the head 30 and shoves the rod 29 up into the position of Figure 3, the crutch 31 raising the gate 47. The projections 35 are rounded so that when the head 30 moves downwardly, it can pass the projections and engage beneath them, as shown in Figure 10.

When the train, moving in the direction of the arrow A in Figure 1, gets to the ramp S, it does not shove this ramp down and c ose the gate 47 again. This is so because the flange of the car wheels can engage with the ends 12 of the ramp 8 and swing it horizontally without forcing it down. Figure 9 shows how this operation is carried out in connection with the ramp 7 when the train is moving in a direction opposite to that indicated by the arrow A in Figure 1.

In the form shown in Figures 13 and 14, parts hereinbefore described have been designated by numerals previously used, with the suffix a.

The modification resides in a change in the train-operated means for reti-acting the slide 25)-30 of Figure 3 to close the gate, the racks 18-20, and the pinion 22 of Figure 2 being replaced by a structure now to be described.

On the inner end of the shaft 23a there is an arm 50 having transversely extended lingers 51 provided with elongated slots 52 in which anchors 53 (such as eye bolt-s) are adjustably clamped. The outer ends of flexible elements 54 are connected to the cranks 16a, the inner ends of the flexible elements being connected to the anchors 53. The flexible elements 54 extend in opposite directions around pulleys 56, supported for rotation on the cross ties, or elsewhere. One flexible elcment may be carried under the highway 6a through a tubular guide 55, and the other flexible element can slide through fair-leaders 57 on the cross ties.

As to the form shown in Figures 13 and 14, this specification need not be encumbered by tracing out the whole operation again. It is enough to state that in the retraction of the slide 28-30 of Figure 3, motion is derived romthe train-operated means (comprising the cranks 16a of Figure 3) through the flexible elements 54 and the arm 50 on the shaft 23a, it being possible to shift the anchors 53. in the slots 52 ot' the fingers 51 in the arms 50, so that there will be no undesirable amount of slack in the flexible elements 54.

What is claimed is:

1. In a device of the class described, a track rail, a ramp, means for mounting the ramp at one end for swinging movement both vertically and horizontally, spring means for raising the ramp whereby a car wheel going in one direction will depress it, spring means for swinging the ramp horizontally against the rail, the 1amp being beveled on its opposite end whereby a car wheel going in an opposite direction will swing it horizontally without depressing it, a gate mounted for vertical swinging movement, a slide sustaining the gate in open position when the slide is advanced, and means for connecting the slide with the ramp, whereby when the ramp is depressed, it will retract the slidel as the gate closes.

2. rIhe combination with a vertically swinging gate, so pivoted as to close by gravity, of a slide having a ycrutch in which the gate rests detachably, means for mounting the slide for reciprocation, spring means engaged directly with the slidetol advance the slide and open the gate, train operated means for retracting` the slide, thereby permitting the gateto close by gravity and slide in the crutch as it closes, latch mechanism cooperating with the slide to holdy the slide retracted when the gate is closed, and train operated means for releasing the latch mechanism from the slide, thereby rendering the spring means active to open the gate.

3. The combination with a vertically swinging gate, of a slide having a- `crutch in which the lower edge of the gate yis slidably received', means for mounting the slide for right line movement, the slide and said means being disposed atan acute angle to the gate when the gate is horizontal and at an obtuse angle to the gate when the gate is opened, whereby the gate can have longitudinal sliding movement relative to the crutch when the gate is being opened and when the gate is being closed, spring means coacting with the slide to advance it and open the gate, train operated means for rei: tracting the slide, to permit the gate to close,

latch mechanism cooperating with the slide, to hold the slide retracted when the gate is closed, and train operated means for releasing the latch mechanism from the slide thereby to render the spring means active to open the gate. y c

4. In a device of the class described, a vertically swinging gate, a side on which the gate rests removably, and on which the gate f moves longitudinally as tliegate opens and closes, means for mounting the slide for right line reciprocation, spring means cooperating with the slide to advance the slide and open the gate, train operated means for retracting the slide thereby to permit the gate to close, latcn mechanism cooperating with the slide to hold the slide retracted when the gate is closed, and train operated means for releasing the latch mechanism from the slide,

thereby to render the spring means active to open the gate.

In testimony that I claim the foregoing as my own, I have hereto alixed my signature.

EVERETT DANIEL.
